Summary: A study was conducted to obtain nanofibers from modified polyelectrolyte blends using poly (ethylene-alt-maleic anhydride) (PEMA) and poly (ethylene oxide) (PEO). The study found that the conductivity of the blends decreased and the surface tension increased as the quantity of PEO in the blends was increased. Various tests showed that the electrospun nanofibers had good biocompatibility and potential biomedical applications.

Summary: The synthesis of various loline alkaloids was achieved through a series of reactions. The C(7) and C(7a) stereogenic centers were formed by conjugate addition and subsequent oxidation and exchange reactions. The remaining C(1) and C(2) stereogenic centers were formed through a Mannich-type reaction. The synthesis was completed by forming the 2,7-ether bridge and further manipulations.

Summary: The strategy of combining biomolecules and synthetic components to develop biohybrids is becoming increasingly popular for preparing highly customized and biocompatible functional materials, allowing the excellent properties of carbon nanotubes (CNTs) to be applied to biomedical applications. The resulting well-defined composites of CNTs conjugated with relevant biomolecules enable the exploitation of nanoscale properties at the micro- and macroscale, with potential applications in tissue engineering, sensors, and wearable electronics. This review presents the underlying chemistry behind the CNT-based biohybrid materials and discusses the future directions of the field.

Summary: The binding of peptides and proteins through multiple weak interactions is widely observed. Biopanning has been used to exploit this multivalent binding for surface functionalization. Understanding the influence of multivalency on binding interactions and surface behavior is crucial for practical applications. In this study, we investigate the relationship between multivalency and the modulation of the surface work function using 12-mer peptides to functionalize indium tin oxide (ITO) surfaces. We demonstrate that the affinity and modulation of the ITO work function by the peptides are linearly dependent on the number of basic residues in the sequence. The multivalent binding interactions result in a peptide crowding effect, leading to a stronger modulation of the work function compared to single amino acid functionalization. This bioderived molecular platform has the potential to eco-friendly enhance optoelectronic device performance.

Summary: Enantiomers of the low-molecular-weight gelator DBS-CONHNH2, based on d- or l- 1,3 : 2,4-dibenzylidenesorbitol (DBS), were synthesized. Although enantiomeric gels still form when mixtures of enantiomers are used, they are weaker than homochiral gels. The addition of even a small proportion of the opposite enantiomer leads to the loss of nanoscale chirality. Enantiomeric gels encapsulate different enantiomers of the anti-inflammatory drug naproxen, exhibiting thermal and mechanical differences between diastereomeric systems. This study demonstrates the importance of chirality in DBS assembly and its interactions with chiral additives.

Summary: Biomimetic science has attracted significant interest in various fields, including chemistry, biology, materials science, and energy. Biomimetic mineralization involves the synthesis of inorganic minerals under the control of organic molecules or biomolecules, with peptides playing a crucial role as building blocks. Peptides can precisely control the morphology, size, and composition of mineralized materials, and also provide templates for the nucleation and growth of inorganic nanomaterials, offering potential for high catalytic efficiency, selectivity, and biotherapeutic functions.

Summary: The GE81112 series, consisting of three naturally occurring tetrapeptides and synthetic derivatives, is evaluated as a potential lead structure for the development of a new antibacterial drug. A second-generation synthesis of GE81112A is reported, which improves the stereoselectivity of the fi-hydroxy histidine intermediate synthesis and provides a stereoselective approach towards both orthogonally protected cis and trans-3-hydroxy pipecolic acid.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

Summary: In this study, the synthesis of functionalized benzo[a]phenazines and indazolo[2,3-a]quinolines was achieved through Rh(III)-catalyzed oxidative annulation of 2-arylquinoxalines and 2-aryl-2H-indazoles with allyl alcohols. The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
